Alkenes – Lesson & Worksheet – Unit 4 – IGCSE Chemistry
Structure, General Formula, Unsaturation & Isomer Naming

This Synapse Science resource introduces the alkene homologous series from Edexcel IGCSE Chemistry. Students explore the C=C functional group, the concept of unsaturation, and learn to draw and name alkenes with up to four carbon atoms, including unbranched-chain isomers.

TOPICS COVERED – SPECIFICATION POINTS

  • 4.23: Know that alkenes contain a particular functional group (C=C)
  • 4.24: Know the general formula for alkenes
  • 4.25: Explain why alkenes are classified as unsaturated hydrocarbons
  • 4.26: Understand how to draw the structural and displayed formulae for alkenes with up to four carbon atoms in the molecule, and name the unbranched-chain isomers:contentReference[oaicite:0]{index=0}

WHAT’S INCLUDED

  • Editable PowerPoint lesson with theory, diagrams, and naming practice
  • Student worksheet with scaffolded formula drawing and functional group tasks
  • Examples of poly(ethene), poly(propene) and discussion on alkene reactivity
  • Clear explanation of addition reactions and double bond properties

KEY FEATURES

  • Visual explanation of the C=C bond and its role in reactivity
  • Naming and drawing tasks for alkenes: ethene, propene, butene, etc.
  • Clear comparison to alkanes and how unsaturation impacts use
  • Fully aligned with Edexcel IGCSE Unit 4 – Paper 2 (Triple)
  • Classic Synapse Science layout for seamless teaching and revision
